This stereo Class D audio amplifier board is capable of producing 400W per channel power output into 3 Ohm load. By means of Sure Electronics T-AMP technology, this amplifier board achieves high efficiency and features low distortion and low noise level. A low noise, temperature controlled, cooling fan is mounted atop the robust heatsink to maximize heat dissipation. Thermal, over/under voltage, and over current protection circuits are also included to extend the longevity of the amplifier board. This amplifier board has three fixed gain settings or you can use Sure's plug in volume control option.
